To all whom it may concern.

lie it known that I, HARRY C. BUSOIIMANN, a citizen of the UnitedStates, and resident of Indianapolis, county of Marion, and State otIndiana, have invented a certain useful and I do hereby declare that thefollowing isa full, clear, and exact description thereof, referencebeing had to the accompanying drawings.

The object of this invention is to provide, in connection with acetylenegas generators, means for indicating the quantity and condition of thecarbid.

The nature of the invention will be understood from the accompanyingdrawings and the following description and claims.

In the drawings, Figure l is a central Fig. 2 is a section on the line2-2 of Fig. 1. Fig. 3 is transverse section on the line 3-3 of Fig. 1Fig. 4- is a partial vertical section tlnrough the device on the line-l--=t of Fig. Fig. 5 is a section on the line 5-5 of Fig. l.

'lhere is provided an outside tank 10, which may be buried in the groundor not, as desired. lVithin said tank on the bottom there is ahorizontal arrangement of pipes ll, from which four upwardly extendinggas pipes extend to an. annular head 13 through which gas inlet ports orpassageways 14: eX- ln said annular head or ring 13 a number of verticalspiral springs 15 are m unted for sup iorting an annular plate or ring lwhich surrounds the conical portion of a carbid holder 17 and supportssaid holder. When the holder is full of carbid the ring 16 and springswill be depressed, s0 tug will rest upon the annular head 13, but as thecarhid used and the contents of the holder become lighter, the carhidholder will. he forced upwardly by the springs. in Figs. 1 and 4. thedevice is h wn with the parts in. their? idle position.

The outlct ot the carhid holder is in the lower end of the conical endof the holder and is surrounded by a casing 18 and is closed orcontrolled by a conical valve 19, the stem 20 of which extends up and isre ciprocable through the top of the carbid holder, and it is actuatedor moved upwardly by 'a lever 21 fulcruincd between its ends on abracket on top of the holder, and its outer end supports aCarbiddndicator for Acetylene-Generators; i

wei ght 2; which extends into chamber 2t at one sid ETYLENE-GENERATORS.

About midway of the tank annul tank and and is secured to ant casing 25ar partition pl inclined inwardly w h i ch by the gas and water.

lhe operation of the scribed is as follows: suitably charged withgravity will cause the so that its to and the valve ca rbi d town and ofthe gas tank drop down into the pass up within the l support PatentedOct. 24, 1911. Serial No. 616,441.

and operates within a e of the carbid holder. 10 there is an ate 124.secured to the and upwardly s a cylindrical projects above the normalabove the lower end of which is open at the bothe top and is supportedparts so tar do- After the apparatus is water and carbid, gas tank 26 todescend, p engages the valve stem 20,- 19 being depressed lets somewater.

Gas will upper portion 26, and when there becomes a sullicicnt quantityof such gas, it will lift the tank 26 out of cont stem, and then the wcivalve 19, so that no more until the quantity of her or reservoir is suilenable gravity to cause said again and open the valve.

struction automatically The gas passes down tl and 12 out: of the tanl28 to a service pipe with a val has a lid act. with the valve gl'lt 23will close the carbid drops down gas in the gas chamiciently diminishedto tank to descend Hence the con regulates its action. irough the pipesll v, up through the 2-), which is pi pe provided ve 30 within a chamber31, which on the upper end thereof. This entire construction is intendedto be buried with the top of the top of the ground, although tl essary.lVithin the connection with the is provided a vertic apparatus flushwith the iat not ucccasing 23'! and on or in wall of the tank there allydisposed scale orseries of graduations with numerals indicating poundsand h number of holder.

pounds of aving'rct'ercnce to the carbid in the carbid wn, the scale isshown amount of carbid up to one Parallel with said scale 36 in the wallpointer 37 extends, which on the upper end of a rod 10 and vertically toguides 39 secured t. Another rod 10 is ower end of the rod 38, andiprocates through the partind at its lower end is pivoted of the tanklit) of the lever 41 is pivotally connected with a rod 44 which extendsup to the carbid v holder and at it's upper end is pivoted to the carbidholder within the' annular head 13 so as to be reciprocated and actuatedby the carbid holder.

The carbid indicating apparatus operates as follows: When the carbidholder is charged with carbid through the cap-closedcarbid opening 45,the carbid holder will settle down and that will cause the pointeror'indicator 37 to move upwardly to the number indicated by the weightof the carbid. As the carbid is used or consumed, its weight diminishesand the springs correspondingly push the carbid holder, which causes acorrespondingly downward movement of the pointer 37 along the scale 35.,Thus anyone can readily see at anytime how much carbid there is left inthecarbid holder by raising the lid 32 and inspecting the indi cator inthe chamber formed by the easing 31. v

I claim as my invention:

1. An acetylene gas generating apparatus including a carbid holder witha tapering lower portion, an annular plate loosely extending around thetapering portion, springs ary means in which said springs are mounted, ascale with weight graduations, and means actuated by the movement ofsaid carbid holder and movable along said scale for indicating theweight of the carbid in the carbid holder.

2. An acetylene gas generating apparatus including a main tank with avertical slot in the wall thereof, weight graduations adjacentsaid'slot, a carbid holder within the tank, yielding means forsupporting the same so'it may have vertical movement, a lever mountedwithin the tank, a connecting rod from said lever to said carbid holder,whereby the carbid holder actuates the lever, and an indicating rodconnected with and actuated by said lever and having pointer projectingthrough said slot.

' i In witness whereof, I have hereunto affixed my signature in thepresence of the witnesses herein named.
